You give no indication but I assume this is directed to me. :shrug: There's nothing to be considered. Would you even take one moment of your time to ponder it if I claimed my dog and cats fly around at tree-top level and catch birds in mid-flight 50 feet off the ground???? His "idea" is just as nonsensical.
If you said that to me in grave seriousness I would ask if you tied them to some kind of model airplane or something. I would ask you to show them to me if you could. Even if you were crazy it would at least be amusing to see what you thought was your dog and cat flying around a tree. And if I genuinely thought you were crazy (not well) I definitely wouldn't get angry and start attacking you to sustain my beliefs about what's possible. What would be the point? Maybe you figured out a way to transplant wings to a dog or cat? I don't know.
Ok I'll call your bluff - name and cite 7 scientists who have done this in the past 24 months failure to respond will be classed as a retraction of this comment
When someone has real conviction I give them the benefit of the doubt. If it was clearly said in jest of course I wouldn't bother.
